@intelnavi you need the latest version of nmap
Um, it's 7.4. I downloaded it this AM from the nmap site, latest stable.
@CrazySeajay, did you put the script on the parent directory c:\Program Files (x86)\Nmap, it works fine on my end
I did and still get the same error. Is this the correct script?
https://github.com/cldrn/nmap-nse-scripts/blob/master/scripts/smb-vuln-ms17-010.nse
Apparently the script had an error, it got updated an hour ago and now works.
Hi Guys,
I am also getting the same errors as @CrazySeajay.
I am fully up to date and have the latest script mentioned. Any pointers as to what i am doing wrong? Im using windows..
Here is the output from nmap
NSE: failed to initialize the script engine:
C:\Program Files (x86)\Nmap/nse_main.lua:259: C:\Program Files (x86)\Nmap/scripts\smb-vuln-ms17-010.nse:1: unexpected symbol near '<\239>'

QUITTING!
Looks to maybe be a problem with the packaged nmap scripts? Any help appreciated.
Thanks

Hi,
Would anyone be willing to help me for a fee? please DM me and we can discuss.
Judging by the "<\239>" appearing, I wonder if you saved the link to the github page, not the file itself.
Try this one (raw output):
https://raw.githubusercontent.com/cldrn/nmap-nse-scripts/master/scripts/smb-vuln-ms17-010.nse
Either Save it, or copy and paste its contents into a file.
@corycorycorycory - You were right! Thanks alot! Great spot...
what dose that mean?

Hello all,
I have the same issue, event that my pc alreadly up to date all windows update
Regards
HIEUPT
Hello all,
I known why the output is " smb-vuln-ms17-010: Could not connect to 'IPC$' " when scan smbv1. It is because we disable smb version 1 on that PC. So to check the patch update is ok or not, reopen smbv1 on it and run script againt
Rgs,
Hello, I made a script in linux to search the network, I hope it helps you, you can modify whatever you want.
#/bin/bash
#######################################################################################################
Author: Sergio Wolf
Description: Search the net on vannacry - MS17-010
Date: 05-16-2017
#######################################################################################################
Requirements:
OS: CENTOS v.7 or others linux
NMAP: Nmap version 7.40 using smb-vuln-ms17-010.nse
#######################################################################################################
To run create the file list_range_ip.txt and include the network or the ips that will be searched.
After 10 minutes you will do a new search.
The result will be in the virus directory, it will be the ip that should be analyzed.
The ips that you do not want to be searched for should be included in the blacklist.txt file.
Modify the script as you wish and use it.
Executing nmap with super-user.

You can change "nmap -sn" to "nmap -sL" to search all addresses.
Rgs,
Lua 5.2's string library doesn't support pack and unpack and that's why you get:
/usr/bin/../share/nmap/scripts/smb-vuln-ms17-010.nse:94: attempt to call field 'pack' (a nil value)
You can use string.char and string.byte to replace these with some work. Be careful with the number of bytes when packing.
Older versions of nmap don't have the stdnse.debug[12] calls:
smb-vuln-ms17-010.nse:88: variable 'debug1' is not declared
You can replace those with nmap.log_write("stdout", string.format calls.
I am currently doing this in a local lab and experienced the "could not connect to ipc$" error. To confirm that my system was indeed patched I executed the following steps (NOT recommended if you are running a production instance) -
- Enable file and printer sharing
- Disable firewall
- Allowed Guest logon for SMB share
- Enabled SMB v1 (this is disabled by default). Run the following command to enable it.
Enable-WindowsOptionalFeature -Online -FeatureName smb1protocol
That helped me the following result:
smb-vuln-ms17-010: This system is patched.
So I got the script, but get an error trying to run it.
